摘　　要：脱碳液中铁含量测定,采用盐酸和乙酸-乙酸铵缓冲溶液取代原方法中的乙酸调溶液酸性,改善了工作环境,简化了操作,且结果准确可行。Uses hydrochloric acid and acetic acid-ammonium acetate buffer solution instead of acetic acid to adjust the solution acidity in determining iron content in CO2 removal solution. The woorking environment is thus improved, the operation is simplified,and the result is feasible and accurate .

关 键 词：脱碳液 铁含量 取代 乙酸 盐酸 缓冲溶液 酸性 简化
